Change in Metal Material Behavior: Vray 7 vs older Vray versions

[Lindhout]

I've noticed a significant change in how metal materials behave in Vray 7 compared to previous versions, and I'm hoping someone can help clarify this.

In Vray 6 and earlier versions, I would create metal materials using this setup:

• Black/dark grey diffuse
• Metallness set to 1
• Specific reflection colors to achieve different metal types

However, in Vray 7, this same setup produces unexpected results:

1. The material appears completely black when using a black diffuse
2. The reflection color settings seem to be ignored entirely

I've found a workaround by moving the reflection color to the diffuse slot, which produces results similar to previous Vray versions. However, I haven't found any documentation about changes to metal material creation in Vray 7.

Has anyone else experienced this? Is this a deliberate change in how metal materials should be created in Vray 7? Any insights would be greatly appreciated.

This is a specification change for V-Ray 7. There is no solution.
